  2. Pfisterer Group - Wikipedia

    en.wikipedia.org/wiki/Pfisterer_Group

    By acquiring Lapp Insulators, one of the largest providers of high-voltage insulators made of ceramics and compound materials, the group secured a leading position on the global market for high-voltage insulators. [15] Pfisterer's newly developed Crosspower hybrid power system was also deployed in the field for the first time in 2015.

    The original insulators used on the river spans were a unique style developed by the Lapp Insulator Co. of LeRoy, NY (the prevailing wisdom being the need to compensate for the higher humidity in the area of the river; standard 'post' style insulators were later installed as replacements when the original insulators failed).

    Victor Insulators, Inc. based in Victor, New York (founded 1893 by Fred M. Locke) is the oldest insulator company in North America. They originally made glass insulators for electrical lines. They suspended operations during the Great Depression , but resumed operations in 1935 as Victor Insulators.

  6. Insulator (electricity) - Wikipedia

    en.wikipedia.org/wiki/Insulator_(electricity)

    Insulators are characterized in several common classes: Pin insulator - The pin-type insulator is mounted on a pin affixed on the cross-arm of the pole. The insulator has a groove near the top just below the crown. The conductor passes through this groove and is tied to the insulator with annealed wire of the same material as the conductor. Pin ...

    The Laboratoire d'Annecy de physique des particules (in English the Annecy Particle Physics Laboratory), usually abbreviated as LAPP, is a French experimental physics laboratory located in Annecy in the Haute-Savoie department of France.

  8. Charge-transfer insulators - Wikipedia

    en.wikipedia.org/wiki/Charge-transfer_insulators

    Charge-transfer insulators are a class of materials predicted to be conductors following conventional band theory, but which are in fact insulators due to a charge-transfer process. Unlike in Mott insulators , where the insulating properties arise from electrons hopping between unit cells, the electrons in charge-transfer insulators move ...

    en.wikipedia.org/wiki/Whitall_Tatum_Company

    Whitall Tatum entered the insulator manufacturing market in 1922, mass-producing them for use on power and communications lines across the country. Armstrong Cork Corporation purchased Whitall-Tatum in 1938, continuing insulator production under the Armstrong trademark. Production continued after a 1969 purchase by Kerr Glass Manufacturing ...
